Once I had the data in the right format I had to plot it on the map. I reworked some of the code from other layers that used googlespreadsheets to accomplish this goal. There were several steps to this process though that were not explained very clearly. To be able to see my changes I had to use browserify (which lets you bundle up all your dependencies) to be able to take my pfaslayer.js file usable to the index.html example file.
It took making a layer file, pfaslayer.js in this case, in the src folder. Then requiring the pfaslayer.js in another file, then browserfying that file and loading this new file in index.html. I also had to update the index.html file to include this new layer onto the leafleft map.
